A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description:
- linux-lts-backport-oneiric: Linux kernel backport from Oneiric
Details:
Somnath Kotur discovered an error in the Linux kernel's VLAN (virtual lan)
and be2net drivers. An attacker on the local network could exploit this
flaw to cause a denial of service. (CVE-2011-3347)
Sasha Levin discovered a flaw in the permission checking for device
assignments requested via the kvm ioctl in the Linux kernel. A local user
could use this flaw to crash the system causing a denial of service.
(CVE-2011-4347)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 10.04 LTS:
linux-image-3.0.0-17-generic 3.0.0-17.30~lucid1
linux-image-3.0.0-17-generic-pae 3.0.0-17.30~lucid1
linux-image-3.0.0-17-server 3.0.0-17.30~lucid1
linux-image-3.0.0-17-virtual 3.0.0-17.30~lucid1
After a standard system update you need to reboot your computer to make
all the necessary changes.

Ubuntu Security Notice USN-1408-1
March 27, 2012
linux-fsl-imx51 vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary:
The system could be made to crash under certain conditions.
Software Description:
- linux-fsl-imx51: Linux kernel for IMX51
Details:
Louis Rilling discovered a flaw in Linux kernel's clone command when
CLONE_IO is specified. An unprivileged local user could exploit this to
cause a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 10.04 LTS:
linux-image-2.6.31-612-imx51 2.6.31-612.34
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.

Ubuntu Security Notice USN-1197-7
March 27, 2012
ca-certificates-java vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
Summary:
A certificate authority mis-issued fraudulent certificates.
Software Description:
- ca-certificates-java: Common CA certificates (JKS keystore)
Details:
USN-1197-5 addressed an issue in ca-certificates pertaining to the Dutch
Certificate Authority DigiNotar mis-issuing fraudulent certificates.
This update provides the corresponding update for ca-certificates-java.
Original advisory details:
It was discovered that Dutch Certificate Authority DigiNotar had
mis-issued multiple fraudulent certificates. These certificates could allow
an attacker to perform a "man in the middle" (MITM) attack which would make
the user believe their connection is secure, but is actually being
monitored.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
ca-certificates-java 20110912ubuntu3.1
Ubuntu 11.04:
ca-certificates-java 20100412ubuntu0.11.04.1
Ubuntu 10.10:
ca-certificates-java 20100412ubuntu0.10.10.1
Ubuntu 10.04 LTS:
ca-certificates-java 20100406ubuntu1.1
After a standard system update you need to restart any application using
ca-certificates-java to make all the necessary changes.
